Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.2% of tests record it — this model is 4.3× that share |
| The 256 models compared | 14 of 256, highest first |
| The model's own record | 504,935 tests · every year of the C4 → |
A share of tests is not a probability for your car: it counts every Citroen C4 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
